How to Measure Ketosis

There are 3 common ways to measure Ketosis

  1. Urine - Keto Strips
  2. Blood - Ketone Blood Meter
  3. Breath - Ketone Breath Meter

1. Keto Strips

The colour on the ketone strip corresponds to the level of ketones in your urine. This is probably the most economical way yet the least accurate way to measure if you are in ketosis. However if you use them consistently you can see how much you have changed over time.

2. Blood Ketone Meter

Firstly I hope you're not afraid of seeing your own blood, it's only a small drop so it should be fine. All it takes is one prick, then placing the drop of blood onto the keto test strip, and into the blood ketone meter. This method is pretty accurate, and is our most recommended way to measure ketone levels.

3. Ketone Breath Meter

These have been popping up across social media and seem to be becoming quite popular. We have not tried them, however we have read many positive reviews. Some of the common ones are "Keyto" and "Breath Track". All you need to do is blow into the tube, similar to a breathalyser, then look at your reading. This is probably the easiest way, and of-course the most expensive.


Light Ketosis: 0.5mml - 1 mmol

This is an ok level to be. And for people trying out the keto diet for the first time this is a great achievement to reach this level.

Optimal Ketosis: 1.0 - 3.0 mmol

This is the optimal place to sit for fat burning and all of the health and energy benefits of ketosis.

Therapeutic Ketosis: 3.0 - 5.0 mmol

Generally, you would only aim for a higher level of ketosis when you are under the reccommendations form your doctor for a specific health condition.
